    Details introduction

    Equipment Overview

    The HVAC air conditioning training assessment equipment is an innovative product developed specifically to meet the needs of vocational education including engineer university,polytechnics,vocation schools. 

    The design concept of the Household Central Air Conditioning Training Device is to simulate a real working environment, so that students can learn and master air conditioning and refrigeration technology in a simulated working scene. By using this device, students can have a deep understanding of the working principle of household central air conditioners, including key parts such as refrigeration cycle, air flow, and control system. At the same time, students can also become familiar with the installation, commissioning, maintenance, and fault diagnosis of air conditioning equipment through practical operation.

    The HVAC lab teaching model is powerful. This air conditioning trainer is not only suitable for the teaching of refrigeration technology, refrigeration fluid machinery, principle and maintenance of household refrigeration equipment, cold storage and refrigeration technology and other related courses in higher vocational colleges and vocational schools, but also can be used as a training base for professional qualification certification such as refrigeration equipment repairman (primary, intermediate, senior). In addition, the air conditioning trainer also supports the teaching of a variety of refrigeration equipment maintenance related courses, such as "Refrigeration Equipment Repairer (Senior)", "Principle and Maintenance of Refrigeration Equipment", "Operation, Installation and Maintenance of Refrigeration and Air Conditioning Devices", "Central Air Conditioning Worker (Primary, Intermediate, Senior)", "Principle and Maintenance of Household Refrigeration Equipment", etc.

    Equipment Features

    1. One-to-three structure: The DLZL-CAC01 household central air conditioning training device system uses one-to-three units . Each execution object is an independent module. It uses three types of terminal processing units: patio type (embedded), wall-mounted type, and fan coil. One air conditioner outdoor unit drives three refrigeration units to start. All are installed on a universal aluminum profile platform, and each execution object and electrical control circuit are constructed. Let students understand the diverse structural forms of indoor units more intuitively .

    2. Open design : The industrial refrigeration trainer has the function of disassembly and assembly, which can be used to train the disassembly and assembly of different forms of terminal equipment. The refrigeration recovery system device is used to achieve the reuse of refrigerant in the process of repeated disassembly and recovery, which is efficient and environmentally friendly. Each terminal processor is equipped with a refrigeration system flow board, a control circuit flow board, a temperature gauge and a pressure gauge, and all control circuits of the unit can be observed.

    3. True restoration: The control function, protection function and display function are completely consistent with the actual household central air conditioner. Each user terminal can be independently controlled under the same working conditions. The training device system is equipped with a simulated fault setting function to set faults in the refrigeration system and electrical system. Through specific phenomena, students' analytical ability is improved, which is conducive to students applying theory to practice and cultivating their practical skills.

    4. Automatic protection device : This industrial refrigeration trainer is equipped with a current-type leakage protection device. When the leakage current to the ground exceeds a certain value, the circuit breaker will trip and cut off the power supply. There is also a thermal protection device to protect the compressor from overheating and overload.


    Application Scenarios

    Train with real-world HVAC systems: The DLZL-CAC01 enables hands-on learning of installation, operation, maintenance, and fault diagnosis of household central air conditioners.

    Ideal for:

    • Vocational colleges & technical schools – practical training for students

    • Enterprise training centers – upskilling HVAC engineers and technicians

    • Skills competition bases – preparation for national and international contests

    Why it works: Students and professionals gain real-world experience, master industrial-standard procedures, and build skills that directly translate to the workplace.
